一、概述变、配电所“微机综合自动化系统”包括了微机保护、微机监测、微机控制、微机通讯及微机日常管理等多个方面的内容,是常规的配电所二次设备的更新换代产品。它的实现可大大地提高供电系统的供电质量、供电可靠性及运行管理水平。长期以来,铁路10KV变、配电所的二次设备主要是由传统的电磁式继电保护和强电控制方式构成。继电器和开关接点存在着氧化、粘连、机械卡死等问题,变配电所内设备故障较多,保护拒动、误动和越级跳闸现象时有发生,严重影响了铁路运输安全,远远不能适应市场经济日益
First, an overview of change, distribution “microcomputer integrated automation system ” includes computer protection, computer monitoring, computer control, computer communication and computer management, and other aspects of the routine, is the secondary distribution of conventional equipment Replacement products. Its implementation can greatly improve the power supply system power supply, power supply reliability and operation and management level. For a long time, the railway 10KV variable, distribution of secondary equipment is mainly composed of the traditional electromagnetic relay protection and strong electric control form. Relay and switch contacts there are oxidation, adhesion, mechanical stuck and other issues, substation equipment failure more, the protection of rejection, misoperation and tripping phenomena occur from time to time, has seriously affected the safety of railway transport, far from being able to adapt Market economy is growing
